Su Wan was originally a wealthy lady, but due to the bankruptcy of her family business, she fell from the clouds to the bottom overnight. Her father died unexpectedly and her mother was seriously ill in bed. Faced with huge debts and the cold eyes of the public, she was forced to transform from a rich and wealthy girl into a "desperate mistress" in the workplace. Starting as a low-level waiter in a five-star hotel, Su Wan encountered countless difficulties and humiliations, but also met Cheng Xu, the hotel chef who gave her warmth in the predicament, Lu Chenzhou, a business upstart who seemed indifferent but secretly helped her, and Gu Mingyuan, her childhood sweetheart but opposed to each other. In the entanglement of emotions and interests, Su Wan gradually uncovered the truth about the family's bankruptcy. She was reborn in the ups and downs of the business world, and found her own shining star in three completely different relationships.
